This semester long course focuses on two core geospatial field methods and technologies: GPS (global positioning systems) and field data collection tools using integrated GIS and GPS (e.g. Survey123, ArcGIS Field Maps, and others). At times we will compare some of these tools and methods to more "old school" field methods. Main topics in GPS discussed are: use of different levels/grades of GPS instruments and peripherals; best practice data collection for point, line and polygon surveys; different methods of both real-time and post-collection differential correction; and assessment and improvement of accuracy/precision. Main topics in field data collection tools are: use of Field Maps / Survey123 to acquire point, line and polygon features; development of and use of forms in Field Maps and Survey123 for field data collection and planning; and overall spatial data collection project design.
